Question
Which of the following best describes the purpose of
data wrangling?Solution
Data wrangling, also known as data munging, involves transforming and cleaning raw data into a structured format suitable for analysis.

Effective data wrangling makes analysis more efficient and reliable by ensuring the data is clean and usable. Option A is incorrect because storing raw data does not involve any transformation. Option B is incorrect as model building follows data wrangling. Option D is incorrect because creating dashboards is for data presentation, not wrangling. Option E is incorrect because KPIs are derived post-wrangling and analysis.
